The 135-degree split point tip engages the work surface on contact, eliminating the bit walking common with standard 118-degree points. A patented core diameter geometry distributes stress more evenly along the shank, reducing breakage under load. The black oxide finish lowers friction and extends service life compared to uncoated high-speed steel. This bit ships in a 3-pack, making it a practical choice for job-site stocking by electricians, plumbers, HVAC techs, and general contractors who go through drill bits regularly.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for use on steel framing, pipe hangers, electrical panels, junction boxes, and structural wood members encountered in residential and light commercial work. The 7\/16 inch diameter is commonly used for anchor bolt clearance holes, conduit knockout punches, and lag screw pilot holes. The 3-pack quantity supports multi-crew applications or reduces downtime when a bit dulls mid-job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point starts on contact and prevents walking without a center punch\u003c\/li\u003e\n  \u003cli\u003ePatented core diameter design reduces bit breakage under drilling stress\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating increases wear resistance and reduces friction versus bare HSS\u003c\/li\u003e\n  \u003cli\u003e7\/16 inch diameter suits anchor clearance holes, conduit work, and lag screw pilots\u003c\/li\u003e\n  \u003cli\u003eSold as a 3-pack for job-site stocking efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stocking drill bit compatible with standard 3-jaw drill chucks and right-angle drill attachments used in trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a compatible drill chuck and tighten securely before use. Always wear appropriate eye protection when drilling metal or masonry-adjacent materials. When drilling through metal, use a cutting fluid or lubricant to extend bit life and reduce heat buildup. Ensure the workpiece is secured before drilling to prevent rotation or shifting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 135 degrees split point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEWALT ACCESSORIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW1128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51563165712690,"sku":"DW1128","price":44.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d06ba097703b98495efcfdd522a1fb93.jpg?v=1786491998","url":"https:\/\/voomisupply.com\/products\/dewalt-accessories-dw1128-black-oxide-drill-bit-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
